The South Vietnamese and their US advisers planned to attack Ap Tan Thoi from three directions to destroy the VC force by using two provincial Civil Guard battalions and elements of the 11th Infantry Regiment, ARVN 7th Infantry Division. The infantry units would be supported by artillery, M113 armored personnel carriers (APCs), and helicopters.
